To all whom it may concern:

Be it known that I, J oIrANN KREMENEZKY, a subject of the Emperor of AUStIlEL- ITIIIH- Hungary, have invented certain new and useful Im rovements in Apparatus for Working G ass in the Heat ;\and I do hereby declare the following to be a full, clear, and exact description of the invention, such-as will enable others skilled in the art to which it appertains to make and use the same- This invention relates to apparatus for working glass in the heat. Such apparatus are more particularly designed for working the bulb blanks. of electric incandescent lamps on sealing into them the filament carriers with the filaments mounted thereon but it is also applicable in many other-cases In the accompanying drawing Figure 1 is a side elevation partly in section of the improved apparatus. Fig. 2 is a similar view of a modification of the apparatus.

In the ap aratus shown and designed more 'particuihrly for sealing the filament carriers into the bulbs of electric incandesgether so as to revolve around the same axis simultaneously and serving for holding the glass parts to be Worked. As shown a is the double ring for supporting the bulb blank and b is the spindle for sup orting the filament carrier. Either or bot h of these parts may be'adjustable axially relatively to the well known blow pipe aratu's not shown in any known or suita b ie manner for instance that used'in the ordinary sealing in articles to be heated at will. I

So far the present apparatus is similar to the sealingin machines now in use. According to Fig 1 the two parts a b are jour naled in a stationary sup ort c and are profi iction wheels (1 e which are coupled by 'pinions orrollers'f g (respectively on a common shaft k).. Anyv revolved in any suitable way, as shown by toothed or friction gearing i, k. r v In the modification shown in Fig. 2 the ing its hollow shaft m driven by a toothed or frictional gearing '5 7c.

In the construction shown in 1 only as shown in this figure the bulb blank an the filament carrier of an electric incandes cent lamp) revolve in the stationary support 0. This enables the glass softened suitable toolby hand.

by the flames of the blow pipe apparatus to be worked by applying against the same a In the construction shown in Fig. 2 the frame 1 revolv'es together with the glass so that the tool cannot be applied by hand against the glass. In order to enable the glass to be worked in the apparatus shown in Fig. 2 through the hollow shaft m another hollow shaft 11. carries at its upper end extending into the frame Z a head 1 pivotally connected by a link 8 with a lever t having its fulcrum on a ring q, this ring is sup orted by rods p passing 'freely through the ead r and secured to a plate 0 free to revolve in the frame Z but prevented frommoving axially in the same. The levert carries at its outer end a roller or arm '11. acting as a tool for working the glass. The rods 1) thus couple the ring g and the plate 0 with the spindle n so that they do not revolve with t e frame Z. If new the hollow shaft n is raised by hand the head 1'v slides along the rods 1) and thus through the medium of the links 8 causes the lever t to be turned as the ring qlis'prevented from moving axially by the p ate 0 and the rods 1). Thus the tool u can be applied against the glass with a 7 pressure that can be adjusted at will wherey the soft glass can be worked as may be required while the frame Z revolves together with the glass around the stationary spindle a without being impeded by the head r and the ring g. The spindle b which as shown serves to fold the filament carrier passes through the inner hollow shaft .n and is free to revolve in and to move longitudinally relatively to the same. The spindle b is coupled with the outer shaft m in any suitable manner for instance by a gearing as indicated.

The present apparatus permits the glass softened by the ow pipe apparatus to be worked in the same way as clay is worked on the throwing mill either by applying tools by hand (in the construction shown in Fig. 1) or mechanically (Fig. 2) which is advanta eous for many purposes and more particular y for the manufactured electric glow lamps. In the latter case in scaling in the'filament carrier the bulb ma be given such a shape that it can be fitted into the normal socket even if the supportin frame and the filaments mounted on the ament carrier have a width notably greater than the 'diameter of the normal socket which isthe' case for instance in metal filament lamps.- The invention thus permits to construct metal filament lam s directly for normal sockets and thus to dispense with the sleeves attached to such sockets which heretofore have been necessary 10 for holding the lower part of the bulb and which sleeves had to be insulated from the socket for the sake of safety so that they were expensive. The construction shown in Fig; 1 moreover offers the advantage that the flames of the blow pipe apparatus act abso-- lutely uniformly all around the glass while, in the construction shown in Fig. 2 as well as in the ordinary sealing in machine the vertical parts of the frame lprevent the direct action of the flames on certa n parts of the glass. The

construction shown n Fig. 2 is more particularly designed for existin sealing in machines to enable them to e readily and cheaply arranged accordance with the present invention. Of course in the construction shown in Fig. 1 too the tools may be i secured to the stationary support 0 or to any other stationary part in a manner similar to that usedin turmnglathes instead of applyingsuch tools to the glass byhand.
